WINDOW STRUCTURE.

Application filed October 27, 1924. Serial No. 746,226.

which are preferably constructed of metal and are provided with means for anchoring or securing them to the masonry of the wall m which they are'installed. The form of structure here shown is of the type commonly known as basement windows comprising a frame and sash, and wherein the sash is usually pivotally mounted or hinged to the upper horizontal portion of the frame, al-

v though it is to be understood that the structure may be used for other purposes than basement windows and also that the sash may be vertically hinged to the frame or be rigidly secured thereto. The hinges for mounting the sash in the frame are prefer ably integrally formed from a portion of the metal from which the frame and sash are constructed thus obviating the necessity for the present common use of screws or rivets for securingthe hinges thereto. The hinges are also so designed that the sash may readily be detached from the frame forwashing or replacement of glazings, without the use of tools. Means. are provided on the frame whereby the usual screens and storm A sash may readily be secured thereto. The

sash is also provided with a novel locking means which is preferably mounted in one or more of the muntin bars thereof and is adapted to coo erate with means in the frame to secure y lock the sash thereto. The construction of this novel frame and sash very'simple and inexpensive, andis such that it may readily be manufactured on a production basis, thereby greatly reducing the manufacturing costs of the structure. The structure herein shown is an improvement over the form of window structures shown in my prior pending application filed November 21, 1923, Serial No. 677 ,O iO.

The object of this invention therefore is to provide animproved window structure.

Other objects of the invention will more fully appear from the following description and the accompanyingdrawing's and will be pointedout in the annexed claims.

In the accompanying drawings there has been disclosed a structure designed to "carry out the objects of the invention, but. it'is to be understood that the invention is not con-V fined to the exact features shown, as various changes may bemade within the scope of'the claims which follow.-

In the drawings: 7

Figure 1 is a front "ew of the structure showing-the sashin closed locked position;

Figure 2 is a rear view of Figure 1 showingthe means provided thereon for securing thereto the screen=orstorm sash;

Figure 3 is an enlarged detail sectional view on. the line 33 of Figure 1, partially broken away, and additionally showing how the frame of the structure is'preferably secured to the opening in the basement wall;

Figure 4 is a partial sectional view-of the structure showing the means provided for retaining the sash in open position;

Figure 5.is a detailsectional view on the line 5-5 of Figure 3;

Figure 6 is a detail plan view of the lower horizontal member of therframe showing the means provided therein for retaining the sash in open position as shown in- Figure;

Figure 7 is a detail view of a lower portion of the sash showing" one of'the'muntin bars secured thereto and. also showing how the locking bolts for locking the sash to the frame are preferably mounted in the muntin bars;

. Figure 8 is a horizontal sectional view on the line 8--8-of Figure 7;

Figure 9 is a vertical sectional view on the line 99 of Figure 7 and Figure 10 is an enlarged detail view showing the socket provided on the lower frame member to receive the end of the locking bolt to lock the sash to the frame.

The, frame of the novel window'structure featured in this invention preferably comprises upper and lower members and end or side members. These frame members are preferably substantially Z-shaped in crosssection as particularly shown in Figures 3 i and '5 and are suitably secured together at the corners of the frame by such means aswall 14 will be outwardly presented while the inner wall 15 will be inwardly presented. Referring to Figures 3 and 5, 1t will be seen that the inner wall 15 of the frame is preferably narrower than the outer wall 14 so that the inwardly projecting edge 17 of the outer wall will overhang the inner rounded edge 18 of the inner wall 15, thereby providing a dual seat against which the sash is adapted to be seatedv as shown in the drawings. It will be seen that the area defined? by the outwardly projecting edge 19 of the outer wall is relatively greater than the area defined by the outer edge 21 of the wall 15, so that the outer edge 19 will thereby overhang the outer edge of the inner wall 15. Thus, when the frame is positioned within the opening provided inthe wall of the foundation or building as shown in Fig ures 3 and 4 and 5, the frame will be supported by the outwardly projecting corner or edge 19 of the outer wall 14, and-the triangular space between the inner wall 15 and the inclined wall 16 may then be filled in with mortar or masonry to securely anchor the frame to the foundation. Integral loops 22 are preferably pressed out of the metal of the outer wall 14 of the upper frame member to provide additional means where by the frame may be secured to the wall of the foundation or structure. Nails may be inserted into these loops and driven into the wall or joists, as indicated by the dotted lines in Figure 3 thereby holding the frame permanently in place.

Means are also provided on the outer walls 14 of the end frame members for securing the usual storm sash or screen to the frame, such means preferably consists in outwardly bending or forming. a portion of metal, as

' particularly shown in Figure 5, to form loops 23 adapted to receive a suitable fastening means provided for securing the storm sash or screens to the frame. I have here shown two such loops on each. side frame member. Similar loops 24 are provided in the outer wall of the lower frame member. These loops are preferably arranged relatively close to the lower edge 19 of the frame and function to provide a drain for water which might get into the triangular space 25 provided between the outer wall 14 and the inclined wall 1.6 of the lower frame member.

The novel sash featured in this invention is preferably constructed of metal and so formed as to have a cross-section of irregular shape. An outwardly projecting marginal flange 26 is provided on the sash adapted to overlap the inwardly projecting edge 18 of the inner wall 15. This flange is adapted to "be seated against the inner face of 'thewall 15 as shown ,in Figures 3 and 5. A seat 27 is provided on the outer portion of the sash and is adapted to be seated against the inner face of the outer wall 14. As here shown the wall of the sash is also formed to provide an outwardly projecting flange 28 adapted to be fitted within the outer portion of the sash and also to provide a drip to prevent water flowing over the surface of the glazings from entering the triangular space 25 of the frame. A

seat 29 is provided in the sash frame adapted to receive a pane of glass 31 which may be secured thereto by such means as the usual putty 32. The pane ot'glass is preferably mounted in an intermediate position in the sash as shown, and the metal from which the sash is constructed is so formed as to present an inclined face 33 adapted to encircle the pane, thereby providing a sash of very neat appearance and also of very rugged construction.

The novel means'provided for pivotally connecting the sash to the frame preferably consists in upwardly bending a portion of the inner wall 15 of the upper frame member to form a pair of hooks 34 shown in Figures 3 and 4. The upper portion of the sash is preferably provided with a pro jecting inclined flange 35 which functions to reinforce and strengthen the upper por tion of the sash when connected to the frame. upper flange 26 of the sash adapted to re ceive the upturned hooks 34 of the frame whereby to provide a supporting means for the sash when mounted in the frame. Thus it will be seen that by means of the hooks 34 and apertures 36 a hinged connection will be provided for the sash thereby allowing it to he swung to an open position as shown in Figure 4. The upper ends of the hooks 34 are preferably spaced a'suitable distance from the walls 15 of the frame member 11':

so that, when the sash is raised to a substantially horizontal position (shown in dotted lines in Figure 4), the sash may readily be detached from the frame without the-useof tools.- vWhen the sash is mounted in the hooks 34, as shown in Figures 3 and 4, the marginal edge of the inclined flange 35 pr0- vided on the upper portion of the sash will engage the concave faces of the hooks and thereby tend to force the marginal flange Y 26 of the sash against the walls 15, thereby position as shown in Figure 4. When the Apertures 36 are provided in the (See Figsash is in closed position the bar 37 will be swung to thefull line position in Figure 6, in which position it willrbe disposed within the triangular space of the frame and will thus be concealed from view. When it is desired to open the sash the bar 37 may readily be grasped and swung to the position shown in F igure 4, in which position the hook 38 will be brought into engagement with the projecting edge 28 and the bar will thus retain the sash in open position.

In Figures 1 and 2, there is shown a sash comprising three sections,such sections being provided by interposing the muntin bars 41 betwe n the upper and lower members of the sash a d suitably securing them thereto by such means as welding. Referring to Figure 8, it will be seen that the muntin bars 41 are preferably formed of metal and are substantially triangular in cross-section. Each muntin bar is provided with an outwardly projecting flange 42 formed by folding the sheet metal from which the bar is made so that the opposed sides of'the sheet Will'be in abutting relation as shown. By' thus forming the muntin bars, a seat 43 will be provided on each side thereof adapted to cooperate with the seat 29 in the sash frame to provide a continuous seat for the pane of glass when -seated therein, The flange 42 will also provide a division between the sash sections and will form a backing for the putty 32'when the pane ofglass has been seated in the sash and secured thereto.

Another important feature of this invention resides in the novel means provided-for securely locking the sash to the stationary frame of the structure. Such means preferably consists in the provision of suitable locking bolts 45 which are slidably mounted in the muntin bars adjacent the lower portion of the sash. Each locking bar is provided with a finger grip 46 which outwardly projects therefrom through an elongated opening 47 provided in the outer central portion of the muntin bar. This finger grip functions as a means whereby the locking bars may be slidably moved into and out of engagement with the lower member of the stationary frame. An aperture or socket 48 -is provided in the inclined wall 16 of the lower frame'member and is adapted to receive the lower end of the'locking bolt when the latter is moved into sash-locking position as shown infull linesin Figure 3. Thus it will be seen that when the locking bolts are moved from the position shown in Figure 9 -to that shown in full lines in Figure 3, the

- in full lines Figure 9, the lower ends thereof will be moved out of engagement with the sockets 48 and the sash may then be readily opened, as shown in Figure 4.. Apertures 49 are preferably provided in the muntin bars adapted to receive a common form of padlock such as indicated by the dotted lines in Figures 7 and 9 so that the locking bars may be locked in sash-locking position, thereby preventing the sash from being opened until the padlock has been removed from the apertures 49.

In the drawings, there. is shown a window structure of the general shape and form commonly employed in the foundations of buildings but it is to be understood that the window structure may be made in various shape;

and forms and may employ one or more muntin bars; or, if desired, may be made Without the use of any muntin bars. The sash may also be rigidly secured to the frame, thereby eliminating the use of the hinged connection formed by the books 34 and apertures 36 and also eliminating the use of the sashlocks provided by the locking bolts 45. The frame and sash of this novel sti'ucture are also substantially of fireproof c'onstruction thereby providing such a structure which is Well adapted for use in fireproof buildings. By the employment of the dual sash-receiving seat provided by the inwardly projecting edge portions of the spaced walls 14 and15, and against which the sash is seated when in closed position, an air space will be provided around the sash which will prevent cold air from entering through the joint between the frame and sash. The above construction will also prevent the surface of the inner frame wall 15 from becoming frosted in cold weather. It will also be seen that the frame and sash are constructed of "metal thereby providing a very rugged and substantial structure of comparatively basis, thereby greatly decreasing the manu- I facturing cost. In the drawings, I have shown the use of putty for'securing the panes of glazings to the sash frame, but it is to be understood that other means may be employed for the above purpose without dcparting from the invention. Y
